Prescription And Its Parts

A prescription is a written order which is generated by the physician, dentist or another registered medical practitioner (RMP) to the pharmacist to compound and dispense medicines to the patients.

In simple words, the prescription is a piece of paper that is written by the registered medical practitioner (RMP)  according to the patient's disease condition.

Prescriptions contain not only the medicines but also contain all other important information regarding the dose of medicine, when to take it, how to take etc.

The patient, after consulting the registered medical practitioner (RMP) , goes to the pharmacy along with the prescription and hands it over to the pharmacist and then the pharmacist dispenses the medication according to the prescribed order.

The pharmacist creates a bridge between the patient and RMP by supplying the correct medicines, pharmacists not only give medicines to the patient but also gives instructions regarding the use of medicines according to the prescriber's advice.

Prescriptions are written in the native language of the area but some Latin words are also used for indication of dose instructions.
